ThoughtSpot allows you to create derived columns in worksheets using formulas. You create these columns by building formulas using the Formula Assistant. An individual formula is constructed from n combination of operators and functions.
This reference lists the various operators and functions you can use to create formulas.
Operators
Operator  Description  Examples 

and 
Returns true when both conditions are true, otherwise returns false.  (1 = 1) and (3 > 2) = true lastname = 'smith' and state ='texas'
Note: Not available for row level security (RLS) formulas.

if…then…else 
Conditional operator.  if (3 > 2) then 'bigger' else 'not bigger' if (cost > 500) then 'flag' else 'approve' 
ifnull 
Returns the first value if it is not null, otherwise returns the second.  ifnull (cost, 'unknown') 
isnull 
Returns true if the value is null.  isnull (phone) 
not 
Returns true if the condition is false, otherwise returns false.  not (3 > 2) = false not (state = 'texas') 
or 
Returns true when either condition is true, otherwise returns false.  (1 = 5) or (3 > 2) = true state = 'california' or state ='oregon' 
Aggregate functions
These functions can be used to aggregate data.
Function  Description  Examples

count 
Returns the number of rows in the table containing the column.  count (product) 
count_if

group_aggregate 
Takes a measure and, optionally, attributes and filters. These can be used
to aggregate measures with granularities and filters different from the
terms/columns used in the search. Especially useful for comparison
analysis. This formula takes the form: group_aggregate (< aggregation (measure) >, < groupings >, < filters >) Lists can be defined with {} and optional list functions query_groups or
query_filters , which by default
specify the lists or filters used in the original search. Plus (+) or ()
can be used to add or exclude specific columns for query groups.
